Errors related to TSIG (Transaction Signature) authentication for dynamic DNS updates.

TSIG is used to authenticate dynamic DNS update requests. These errors occur when TSIG authentication fails due to invalid keys, mismatched algorithms, or replay attacks.

Variants

TsigConnectionError

TSIG connection or authentication error when attempting dynamic updates

Returned when TSIG authentication fails. This could be due to:

• Incorrect TSIG key name or secret
• Mismatched TSIG algorithm between client and server
• Clock skew between client and server
• TSIG key not configured on the BIND9 server

Fields

server: String

The DNS server (IP:port) where TSIG failed

reason: String

Specific reason for TSIG failure

TsigKeyNotFound

TSIG key not found in Kubernetes secret

Returned when the expected TSIG key secret doesn’t exist in Kubernetes. This indicates a configuration error or missing secret.

Fields

secret_name: String

The Kubernetes secret name

namespace: String

The namespace where the secret should exist

InvalidTsigKeyData

Invalid TSIG key data in Kubernetes secret

Returned when the TSIG secret exists but contains invalid data (missing fields, malformed base64, unsupported algorithm).

Fields

secret_name: String

The Kubernetes secret name

reason: String

Explanation of what is invalid

TsigVerificationFailed

TSIG verification failed (server rejected the signature)

Returned when the BIND9 server rejects the TSIG signature on a dynamic update. This indicates the signature doesn’t match, suggesting key mismatch or tampering.

Fields

server: String

The DNS server that rejected the signature

key_name: String

The TSIG key name that was used

Trait Implementations

impl Clone for TsigError

fn clone(&self) -> TsigError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TsigError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TsigError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TsigError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<TsigError> for DnsError

fn from(source: TsigError) -> Self

Converts to this type from the input type.
